Resets system flags when updating PackageSettings

In the case that we're updating a system app, we will in-place
update the PackageSetting object. This works for most fields but
breaks when updating flag fields as we're executing a binary or
on the existing flags, thus not unsetting bits when we should be.

This change resets all system-related flags before setting the new
flag values.

Test: manual - move app from priv-app to app, install update,
               verify that app does not receive priv flag
